BRAlDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 313,905, dated March1'7, 1885.

Application filed January 23, 1883.

To all-whom it may concern.-

Be it known that I, HERMAN W. W'INANS, of New York city, in the countyand State of New York, have invented certain new and useful Improvementsin Braiding-Machines; and I do hereby declare that the following is afull and exact description thereof.

The objectof the invention is to produce a machine for making squarebraids from c0tton-yarns applied in successive layers one exterior tothe other, either with or without a rubber core, the completed articleto be used as packing for the stuffing-boxes of steam-engines or forother purposes.

The invention is illustrated in the accompanying drawings, which form apart of this specification. and in which- Figure 1 is a plan View, andFig. 2 a side elevation, of a machine embodying my invention. Fig. 3 isan elevation of a portion of the machine, taken at right angles to theview in Fig. 2. Fig. 4 is a vertical detail section showing one of theyarn-guides and a yarn being led up out of it. Fig. 5 is a plan view ofthe shaping-die, and Fig. 6 is an elevation of one of the partscomposing the die.

Referring to the drawings, A designates the rigid frame of the machine,and B B are sets of bobbin-carriers supporting bobbins which delivercotton-yarns upward through guides P. The yarns on emerging from theseguides converge, and as the carriers B B are traversed by ordinarymechanism, delivering the yarns under a uniform or nearly uniformtension, a closely-woven cover is braided around the core Z, led up frombelow through the center of the machine. The completed braid is carriedpartially around two slowly-rotating feed-wheels, and thus caused tomove slowly upward, while thebobbin-carriers B B, traversing in oppositedirections below, properly interlace the several yarns and produce abraided tube, .m, around the core Z.

The bobbincarriers are traversed in their races by the usual forked orslotted carriers, which are operated by a train of connected gearing,these parts being substantially in construction and operation the sameas shown in the Patent No. 191,641, of June 5, 1877.

(No model.)

The braid, so far as yet described, would be produced in a cylindricalform,'or nearly so; but I resist this tendency by introducing in eachsuccessive layer of braid four longitudinal yarns, n, which are arrangedequidistant from each other and serve to build up four corners. Theseyarns n are led up from bobbins, (not shown,) and are conducted throughguides P, and led into the correct position un der the covering or tubeat. A stationary guide, T, which I term a core-die, receives and guidesthe core Z. The hole in the center of this core-die T should be of thesize and form of the core Z. The yarns n are brought into the properrelation to the coreZ by being introduced into notches w, formed in thecorners of a larger die, WV, above. The die WV has a rectangular passagethrough it, slightly flaring at the bottom, and of a size to matchclose- 1y to and to smooth and finish the resulting product after thecover m has been braided on the core Z.

I can make a successful braid bybraiding as described a covering, m, inauniform layer around a compound core composed of the core Z and fouryarns, n, extending equidistant along its surface. In such case thecovering m would be entirely exterior to the longitudinal yarns.

I prefer another construction, which I will now describe. The guides I?stand in the spaces A in the frame A, between the paths or races of theseveral bobbins, and their heights are about equal to those of theseveral bobbin-carriers, B B. As the bobbin-carriers traversesuccessively in their several races alternately outside and inside ofeach guide P they braid the covering m with the corner yarns a embracedwithin its structure. By placing the guides P at equidistant points, asshown, and guiding the yarnsn therefrom accurately into position by thenotches w in the die W, the

yarns n are placed properly to build up the four corners of the braid.Vhether the yarns n are braided in the structure at or are laid at fourcorners independently, they serve to build up those corners, and thebraided article passing up through the flaring aperture in the die Wbecomes pressed and shaped into a smooth rectangular body. The wheels XY a square instead of in a circle, as shown, and

feed the braid slowly forward and upward. The first Wheel, X, is finelytoothed, to aid in its taking afirm hold on the covering m. The otherwheel, Y,'may be smooth. The braid is led from this take-up mechanism toa bobbin, on which it is smoothly wound. In case several layers ofbraid, m, and corner yarns are to be applied, the operation is repeatedon the same machine, ,or on a corresponding ma chine with larger dies Tand W, the article produced by one operation serving as a core for thesubsequent similar operation. The sizes and firmness of the yarns n intheir relation to the yarns of the cover at should be adapted to eachother with the desired purpose in View.

The dies T and NV are made in two parts, held together in a suitableframe, Y, by screws V, as seen in Fig. 5. This construction will allowthe ready change of dies of one size for those of another size ofinterior passage.

The traversing ways for the bobbin-carriers may be formed approximatelyin the figure of a different number of carriers may be used. 2 5

WVhat I claim as new is 1. Thecombination, with the die W, made in twoparts, as shown, of the frame Y and screws V, the corner guides, P, thecarriers B B, and the mechanism for traversing said car- 0 riers inopposite directions, as set forth.

2. The upper die,W,having notches w,adapted to guide the yarns n, asdescribed, combined with the core-die T, bobbincarriers B B, means fortraversing them in opposite direc- 3 5 tions, and the take-up mechanism,as herein specified.

In testimony whereof I have hereunto set my hand, at New York city, this31st day of O0- tober, 1882, in the presence of two subscribing 0witnesses.
